Rebranding your emails sounds simple on paper. New colors, new fonts, maybe a refreshed layout, and you’re done.
But in practice, rebranding email is usually a much bigger lift than that. I’ve worked with teams rebranding over the years, and one thing I’ve noticed is that email rebrands are never just visual updates. They’re usually a mix of audit, cleanup, design work, system thinking, and a lot of practical decisions about how email actually gets made.
Email systems tend to live in a liminal space. A lot of people may be involved in different parts of a creation process that can be spread out over multiple tools, so it can be hard to define the scope of a rebrand, identify the right stakeholders, and set clear priorities. If you want to rebrand your emails well, here are a few lessons I’ve picked up from working with dozens of teams that have done it successfully.
Where to start
The first step is understanding what you already have: start by auditing the emails you’re sending. Pull a list of what your team has sent over the last few months and do a deep dive.
Try to find out:
- Which email templates are your big senders
- Which email templates are your best performers
- Where your customers open their emails
The goal is to understand what kinds of emails you’re sending now, what’s working, what isn’t, and what matters most to your customers.
This is how you decide what to prioritize.
A lot of teams do not need to rebrand everything at once. Usually, it makes more sense to start with your biggest sender emails or the emails that matter most to the customer experience, then work outward from there. Sometimes that process also reveals old templates that can just be retired instead of refreshed.
With that context in mind, you can pull the visuals of all your emails you want to update and get a bird’s-eye view of your email program.
One of my favorite ways to do this is to take screenshots of each email and drop them into a FigJam or some other shared workspace. Once you can see the full program at a glance, it becomes much easier to spot recurring layouts, understand your information hierarchy, and see where things feel inconsistent.
Your rebrand has to survive the inbox
One of the biggest mistakes teams make is assuming email can be rebranded the same way as web or other digital channels. It can’t. Email comes with its own set of design and technical constraints, with plenty of niche design pitfalls to watch out for during a rebrand.
In email, even simple layout changes are more complex than they seem. Styles are inlined. Client support is inconsistent. Accessibility matters. Deliverability matters. Dark mode matters. Gmail clipping matters. And Outlook matters more than anyone wants it to.
That means a rebrand is not just about making emails look more current. It is about making design decisions that will actually hold up in the inboxes your audience uses. If you can, look at your own email client data to see where your emails are opened. If you can’t, a market share breakdown like Litmus’s is a good place to start.
Where your emails are opened matters because different email clients support different design features. If most of your audience opens in Outlook on Windows, your constraints are very different from an audience mostly using Apple Mail on mobile. A design that leans heavily on rounded corners may lose that rounded effect in Outlook on Windows, which does not support border-radius. The same goes for custom fonts: if many of your readers open in Gmail, your carefully chosen typeface will be replaced with Roboto. Knowing where your audience actually opens your emails helps you spend time on design choices they will actually see.
The better you understand your audience’s inboxes, the less time you’ll spend trying to force a shiny new rebrand into email clients that were never going to support it well in the first place. Identify the clients that matter most, learn their quirks, and optimize for them.
(Or find an email markup language that supports all email clients like DML)
Make the rebrand work for the team using it
There is often pressure to make things look dramatically different, but more design is not always better. If one of your best-performing emails is nearly plain text, pay attention to that. If a certain layout keeps popping up, don’t throw it out just because the new brand direction feels like it should be more designed.
The best rebrands are intentional. They keep what is working, change what matters, and avoid adding friction for the people building emails every day.
That matters because extra complexity creates two problems at once: it makes emails harder to build and maintain, and it makes it harder for teams to stay on-brand when they need to move quickly.
In email, the priority is usually getting the right message out at the right time. If you want the rebrand to last, create a design system that makes that easy.
Use a rebrand to improve the email system (since you are already in the thick of it)
This is also why I think a rebrand is a really good opportunity to improve the system itself, not just the surface of the emails. You already have to touch a lot of your email system during a rebrand, so it’s worth thinking about naming conventions, block structure, shared styles, and guardrails. That kind of work pays off long after the rebrand is over.
Modular systems make email rebrands much easier
This is where modular email design makes things dramatically easier.
If you don’t have a modular system, even a small rebrand change can become tedious fast. Say you have a hundred templates with buttons in them, and you want to update the button color.
Without a modular system, someone has to go into every one of those templates and change that code manually.
With a modular system, you make that update once in the shared component and let it carry through. You make the change one time instead of a hundred.
And if your system separates styling from structure even further, as Dyspatch does with Themes, it gets easier again. If color, spacing, and button styling live in a shared theme or token layer instead of being hardcoded into each individual block, then rebranding becomes faster and less brittle than opening every email or even every module to make style changes.
Don't treat marketing and transactional emails the same way.
Marketing emails are usually a more straightforward design and production project. Transactional emails are often much more developer-heavy because they involve dynamic content, product logic, and structured data. A receipt, invoice, or account email is a very different kind of beast than a campaign email.
If you treat all emails the same during a rebrand, you might be surprised when updates slow to a crawl with transactional emails.
Transactional emails often need more engineering support, more careful QA, and a better understanding of what data is available and how it’s being passed into the email. So if you’re planning a rebrand, it helps to separate those workstreams early and be realistic about the lift involved.
Roll out fresh emails gradually
I think gradual rollouts are the safer choice in email, though I understand that teams often want to roll out a rebrand all at once.
Part of why I feel that way is because email programs are rarely as tidy as they look from the outside. The other part of it is deliverability. If something slips past QA and a large volume of email goes out with issues, that can do real damage to your sender reputation.
A phased rollout gives you more room to validate changes, test properly, and catch problems before they hit your whole program.
I also prefer creating fresh versions of emails instead of trying to retrofit every old one in place. It may feel like updating existing templates would be faster, but updating existing email HTML can be a needlessly delicate process. Starting fresh is easier than trying to safely rework existing code you likely no longer have context for.
What I’d tell any team rebranding their emails
If you’re rebranding your emails, start by understanding what you’re already sending.
Look at what performs well. Look at what your audience is opening in. Preserve what is already working. Be careful about adding complexity just for the sake of looking more “designed.” And if you can, use the rebrand as a chance to improve the system behind your emails, not just the visuals.
That's what a successful email rebrand looks like.
It’s more than just an on brand set of templates. It’s a better, more usable, more resilient email system that helps your team move faster and helps your customers get what they need.
